How Anhui Carton Factory Solves the Problem of Carton Collapse
Release Time：2018-12-17 13:56:13 / From：
Some carton factories often face some major problems, that is, the collapse of boxes and the sticking machine is not strong, on this point for carton factories is fatal, it is easy to be described as quality problems, in view of this, Anhui Zhongxia Packaging Title for you to sort out some solutions, hoping to help colleagues and friends.
1. Control the use of base paper
Check the sizing condition of corrugated paper and the water absorption index of base paper. If the base paper surface sizing is poor, the water absorption will be high, and it is easy to be affected by the low temperature and humidity of the hand cold storage, resulting in moisture regain, softening and reduction of the finishing compressive strength.
2. Control the moisture content of cardboard when producing cardboard
The moisture content of cardboard should not be excessive, because the hardness of cardboard is low when the moisture content is large, which affects the edge pressure index of cardboard. In the process of cardboard processing, the glue content of single-sided machine and double-sided machine should not be too large. Once the amount of glue is large, the corrugated shape of the cardboard will be deformed, and the corrugated shape directly affects the edge pressure of the cardboard, and the edge pressure decreases, so does the compressive strength.
3. The bonding strength of cardboard should be high.
The bonding strength is the bonding strength of corrugated paper with lining paper and facing paper. In case of paperboard pseudo-sticking, the face paper or lining paper will be separated from the corrugated paper after compression, and the compressive strength will decrease in a straight line.
4. The gap pressure control in production should be moderate.
Especially attention should be paid to the clearance pressure of pasting on the pasting machine should not be too small. The clearance pressure of the solar wheel on the double-sided machine and die cutting machine should be controlled within a reasonable range to avoid crushing the corrugated shape and affecting the compressive strength of the cardboard.
5. Use water sprinkler and waterproof varnish to solve the problem of surface waterproof and moisture-proof.
